Open Source - Just Another Licensing Model

Let's be clear about this. There are four different reasons for
choosing an open source solution. First, because you want to play
around with the code; second, because you have ethical concerns over
the extent to which proprietary vendors should be allowed to profit
from their products; third, because you think the product is better or
more suitable for what you want it for than any proprietary
equivalent; and fourth, because it is cheaper.
